Semidefinite programs are convex optimization problems involving a linear objective
function and a domain of positive-semidefinite matrices. Over the past two decades, they …

While there is general consensus on the definition of incompatible POVMs, moving up to the
level of instruments one finds a much less clear situation, with mathematically different and …

Given a set of local dynamics, are they compatible with a global dynamics? We
systematically formulate these questions as quantum channel marginal problems. These …

Symmetry is a unifying concept in physics. In quantum information and beyond, it is known
that quantum states possessing symmetry are not useful for certain information-processing …

Entanglement, a fundamental feature of quantum mechanics, has long been recognized as
a valuable resource in enabling secure communications and surpassing classical limits …

The mixedness of one share of a pure bipartite state determines whether the overall state is
a separable, unentangled one. Here we consider quantum computational tests of …

The ideal realization of quantum teleportation relies on having access to a maximally
entangled state; however, in practice, such an ideal state is typically not available and one …

Secret-key distillation from quantum states and channels is a central task of interest in
quantum information theory, as it facilitates private communication over a quantum network …

Quantum non-Markovianity in tripartite quantum states $\rho_ {ABC} $ represents a
correlation between systems $ A $ and $ C $ when conditioned on the system $ B $ and is …

Quantum communication relies on the existence of high quality quantum channels to
exchange information. In practice, however, all communication links are affected by noise …
